When the doors finally reopen at Westfield Montgomery mall, it’s impossible to predict which stores will be coming back. But here’s one thing we know for sure: Forever 21 has reached the end. The teen clothing retailer, in bankruptcy since last fall, will be permanently shuttering its stores at all Westfield malls including Montgomery, Wheaton and Annapolis. (Update: We were wrong on this one. Forever 21 found a buyer and did indeed return when the mall reopened in June.)
